To all whom it may concern:

Be itlmown that l, THOMAS A. Enrsou, s citisen'oi the United States, residing Llewcllyn lsrlr, @renge, county of Essex, and Eltste of New Jersey, have invented certain new and useful Waterproofing Point for Portland-{lenient Buildings, of which the iollowin is description.

l he object of my invention is to provide s sint for application to dwellings or other uildings constructed of fortiend cement,

which. will be entirely waterproof, and which will actually penetrste the pores of the coment surface, even when monolithic, so that the paint will be very permenent.

l have discovered that a very desirable material for this nurpose is that known in the petroleum trade as B. S, such material being eposrently at very heavy hydrocarbon that settles when cruoe petroleum is stored for some time in large tanks. This materiel does not appear to be soluble to any extent petroleum, and under ordinary conditions is probably held in suspension therein, but. when it is permitted to remain quiescent for a. considerable time it settles out. B. 55., so-cslied, I find by investigation, does not undergo any change when exposed to light, moisture, or other atmospheric conditions; besides which it is a material thst'is extremely cheap. I take a. sufficient quantity of the material and dissolve it in it suitable solvent, such as home], petroleum benzine or t .rpentine, in which a lcrgcpert of the meter ti. is soluble. When used inthis cons dition, as e Waterproofing point, the solution applied. to the cement wells with a. brush or otherwise, and the solvent curries the rum teriui some distance below the surface of the slightly porous cement, even in monolithic constructions. The solvent quickly evaporates the B. S. in the pores and coyeri..-,;' the exposed surface. in this condition, the material when so applied is somewhat sticky, and. when this stickiness is undesirable, of course, would be the case for the interior of s house, i add to the solution a. sullicient quantity of strongly boiled linseed oil, which is also soluble in the solvent used. Upon the evaporation of the solvent, the luiseed oil in at short time oxidizes so as to neutruliz he sticky proportiesol' the B. S. paint, witlimit destroying its Waterproofing" and other dosh-chic qualities.

it will, of course, be understood that verious pigments and oil colors may be added to the solution in order to sccure vsrious tints.

The color produced by the use of B. S. Without the addition of other pigments is a light yellow tint.

For the treatment of a roof of a. cement house, instead of applying the B. S. in the form of e'solution, it may he applied directly by melting it to thin liquid and applying it hot to the surface of s. cement root. in the latter case, the nstursl stickiness of themetericl can be neutralized by applying over the seine e fine powder, such as chalk or finely ground cley.

v Having now described my invention, What I claim esnew and desire to secure-by Letters Patent is as follows:

A waterproofing point for cement structures, comprising a petroleum residue known as \B. S. dissolved in it suitable solvent, substantially as set forth.

2. A waterproof paint for cement structures, comprising a petroleum residue, known as B. S. dissolved'in a. suitable solvent, end an additional ingredient to neutralize stickiness, substantially as set forth.

3. A Waterproof paint for cement structures, comprising a petroleum residue known as B. S. dissolved in a suitable solvent, and boiled linseedoil also dissolved in c solvent, substsntielly as set forth.

' l. A Waterproof point for cement structures, comprising as petroleum residue known as B. 8. dissolved in a. suitable solvent and a colored pigment, substantially as set forth. I

A vi sterprooiing paint for cement structures comprising a petroleum residue known as B. 8., dissolved in it suitable solvent, an additional ingredient to neutralize the stickiness, and :i'colorod pigment, substentielly as set forth.

6. A Waterproofing point comprising a. pctroleum residue known as ll. S. dissolved in a suitable solvent, and an additional oxidisable substance, substantially as set forth.
